A cultural movement is a shared effort by loosely affiliated individuals to change the way others in society think by disseminating ideas through various art forms and making intentional choices in daily life.
An obsession emerges among the mainstream with the new movement, and the old one falls into neglect – sometimes it dies out entirely, but often it chugs along favored in a few disciplines and occasionally making reappearances (sometimes prefixed with "neo-").
This is because the movements did not spring out of the blue and into existence then come to an abrupt end and lose total support, as would be suggested by a date range.
In the late 20th and early 21st century in Thailand, for example, there has been a cultural shift away from Western social and political values and more toward Japanese and Chinese.
As well, Thai culture has reinvigorated monarchical concepts to accommodate state shifts away from Western ideology regarding democracy and monarchies.
